This walk proved very popular, and was fully booked within 24 hours.

PNTA members were treated on a sunny day to a short walk across Amroth beach that allowed us to see many geological features, within a short distance. These were highlighted and clearly explained by our walk leader, Chris Evans, a retired teacher and volunteer at Colby NT.

Coal seams, sunken forest, limestone pavements and iron deposits were seen, with rock faults and folds explained. The band of the marker bed, which occurs across the world, was visible in the cliff and at our feet. (See photos.)

The lighter band of the marker bed can be seen in the lower part of the Amroth cliff. Photo by Chris Evans.

Our thanks to Pat Morgan for organising the walk and to Chris Evans for sharing his knowledge, with clarity.
